104  Write a debugger plugin

• Adding the debugger registers profile into the shlr/gdb/src/core.c
• Adding the registers profile and architecture support in the librz/debug/p/debug_native.c and librz/debug/p/debug_gdb.c
• Add the code to apply the profiles into the function rz_debug_gdb_attach(RzDebug *dbg, int pid)

If you want to add support for the gdb, you can see the register profile in the active gdb session using command maint print registers.
